Since I was having problems with the 11.04 release of Ubuntu, I decided to try
Kubuntu again (64 bit version). All was well until I attempted to shut the
system down. When nothing happened with the gui shut down button, I opened a
terminal and executed 'sudo shutdown -h now' which worked after I provided my
password. This leads me to believe that I do not have shutdown privileges as a
user. Is there a way to correct this, or do I have to bring up a terminal every
tim I need to shut the machine down?
